Abstract:
Supernova 1987A (SN 1987A) in the neighbouring Large Magellanic Cloud
offers a superb opportunity to follow the evolution of a supernova
and its remnant in unprecedented detail. Recently, far-infrared
(far-IR) and sub-mm emission was detected from the direction of
SN 1987A, which was interpreted as due to the emission from dust,
possibly freshly synthesized in the SN ejecta.
To better constrain the location and hence origin of the far-IR and
sub-mm emission in SN 1987A, we have attempted to resolve the object
in that part of the electro-magnetic spectrum.
Description:
We observed SN 1987A during July-September 2011 with the Atacama
Pathfinder EXperiment (APEX), at a wavelength of 350um with the
Submillimetre APEX Bolometer CAmera (SABOCA) and at 870um with the
Large APEX BOlometer CAmera (LABOCA). The 350-um image has superior
angular resolution (8") over that of the Herschel Space Observatory
350-um image (25"). The 870-um observation (at 20" resolution) is
a repetition of a similar observation made in 2007.
